Installed the latest CPU Z and yes they show as E5645. However the E-Leet is the latest version that I downloaded from EVGA website so maybe they need to revise it a bit. The rig has stabilized at 52-53k PPD and it has amazing airflow, overclocked at 3.00GHz. In the coming winter, when AC will no longer run I will try to go even further, but not by much. Native Linux install is not in my plans yet as this is still my gaming rig a few times a week.
